SPECIFICATION forming part of Letters Patent No. 482,145, datedSeptember 6, 1892. I

Application filed January 4, 1892. Serial No. 417,032. (No model.)

To all whom it may concern:

Be itknown that I, EDMUND T. VIGG, a subject of the Queen of GreatBritain, anda resident of the city of London, in the Province ofOntario, Canada, have invented certain new and useful Improvements inBurners, of which the following is a specification.

The object of this invention is to provide an improved apparatus bymeans of which heat is obtained from the combustion of the icombinationof the surrounding atmosphere with the vapor generated from gas-oil (alow grade of petroleum) or other liquid hydrocarbon and the perfectcombustion of the same by oxygen taken up and combined therewith fromthe surrounding atmosphere; and it consists of the improved constructionand combination of parts of the same, all of which will be hereinafterfirst fully set forth and described, and then pointed out in the claims.

Reference is had to the accompanying drawings, which form a part of thisspecification, wherein- Figure lis aside elevation of an apparatushaving a double burner embodying my invention and shown in a stove orfurnace, with the front plate of the latter removed to show theapparatus therein. Fig. 2 is a central longitudinal sectional view ofthe apparatus shown in Fig. 1. Fig. 3 is a sectional view of the retorton the line a; x of Fig. l. Fig. 4 is a sectional view of the combinedsuperheater and abutment on the line a a of Fig. l. Fig. v5 is a sideelevation of an apparatus having a single burner embodying my invention.Fig. 6 is a central longitudinal sectional view of the same. Fig. 7 is asectional View of the combined superheater and abutment on the line a aof Fig. 5. Fig. Sis a sectional view of the retort on the line :r o; ofFig. 5.

Any liquid hydrocarbon may be used with perfect safety in thisapparatus; but from the particular construction and operation of anapparatus embodying my improvementsl am enabled not only to burn a largeportion of the surrounding atmosphere as fuel, but to form a perfect andcomplete combustion of gas-oil, (a low grade of petroleum,) which fromits loW price enables me to provide an apparatus the fuel for which canbe supplied at very little expense, and not only this, but when theburner is once started it will continue burning without the necessity ofcontinual supervision which ordinary furnaces require in the person ofan engineer or lireman, so that an apparatus embodying my improvementseffects a large saving in running expenses over those where a moreexpensive fuel is used and where continued supervision is required.

This gas-oil or other liquid hydrocarbon is piped from the tank A to theretort C through pipe B, a valve b in the latter regulating the supplyto said retort C. This tank A is placed in an elevated position, asshown in Fig. l,in which case the oilis intended to be fed by its owngravity. This retort O is formed with the openings C,the sides of whichare walled,

as shown in Fig. 2, to prevent the escape of the contents of said retortat this point, and communicating with the interior of said retort O isthe pipe D and the petcock E, and this retort is also provided with thelugs O2 and @anges O3. The latter extend around the openings O andincrease the length and draft and direct the iiame against the solidunder side of the superheater G, the under side of which forms theabutment.

F designates a nre-pan provided with the slotted standards f', in theslots of which standards the shanks of the screw-bolts which bind thelugs C2 and the standards f together may be vertically adjusted tosupport the retort and attachments at any desired position or elevationin the furnace-chamber.

G designates a combined abutment and superheater, within which is formedthe winding passage G', and the pipe D from the retort C communicateswith this passage G near one end, and with the other end of this passagethe pipe D communicates, and the latter extends down through the retort,and an opening or openings d2 are formed in this pipe D', at which pointthe vapor escapes and is ignited, and where this pipe D extends throughthe retort the latter is walled to prevent the escape of its contents atthis point, and d3 are shields surrounding the pipes D D between theretort C and superheater G to prevent said pipes from being injured bythe action of the heat as the dame rebounds IOO from the under side orabutmentiof the supei-heater G.

The petcock E is used in connection with the retort C in order to drawolf any impurities or refuse which may remain in said retort after theoil is vaporized and also to supply a'little oil to the fire-pan, whichis ignited and heats said retort to commence the operation of vaporizingthe oil therein, which vaporization is afterward continued by theXcom`bustion of the vapor and the surrounding atmosphere as said vapor passesout through the opening d2 in the pipe D'. By opening this petcock Ebefore shutting down the fire or turning oif the supply of liquidhydrocarbon the expanded Vapor rushes out of the retort through thispetcock E and carries with it every particle of impurity in the retort,thus leaving the latter perfectly clean andin the best condition toagain commence the operation of vaporizing the oil. The flame from thecombustion of the Vapor and the surrounding atmosphere passes throughthe opening or openings C and strikes against the under side of thesuperheater G, which forms a solid abutment and retards the ame and heatat this point, which not only causes a perfect combustion of the gas orvapor and air, but heats to a high degree said superheater G, and as thevapor passes from the retort C through the winding passage G it isexposed to and passes over a large area of heating-surface in order tobecome highly superheated and xed into a gas, which passes down throughthe pipe D to the opening or openings d2, at which point it is ignited,as before stated.

l-I H designate screw-plu gs in the retort and superheater, which may beremoved to extract any large impurities from these parts. They aresupplemental, however, and it isonly in exceptional cases that theywould be removed, the petcock E effectively and practically answeringfor this purpose.

K designates a partition-wall formed of any suitable non-combustiblematerial, and it is situated about on a line with the retort C, whichpartition separates the furnace or chamber in which this apparatus isplaced into two apartments, and an opening K is formed in this partitionK large enough for the retort C to rest in, or the partition K may beplaced immediately under and rest adjacent to 'said retort, as shown inthe accompanying drawings, in which case an opening or openings K' areformed therein opposite the openings C of the retort C, so that theseopenings C', extending through the retort C, are the only communicatingpassages between the two apartments of the furnace. The lower apartmeutof this furnace only is provided with suitable ample openings (notshown) for the admission of fresh air, and the only opening which it canpass through from the lower to the upper apartment is the opening oropenings C', and it is drawn through these in large volumes by the forceof the vapor escaping from the opening d2 in the pipe D as it rushesupthrough said openingG,so that all the air passing through the furnace orcham ber in which this apparatus is placed must pass through theopenings C. This brings large volumes of the surrounding atmosphere indirect contact with the burnin gvaponwhich `takes rup the oxygentherefrom, and this, to-

gether with the abutment formed by the solid under side of thesuperheater G against which `the gias or vapor and air strike, causes acornplete and perfect combustion of both to take place;and,further,byusingthispartition-Wall as just described all the airentering the furnace or chamber in which this apparatus is placed mustpass up through the openings C in the retort C.l This enables the feedof the oil to this apparatus tobe wholly accomplished by its gravitationwithout the assistance of air-pumps or other force. r

The operation of the apparatus with a single burner, as shown in Figs.5, 6, '7, and8, is identical with that of the double burner shown inFigs. l, 2, 3, and 4, the only difference being 'in the number ofopenings C through the retort C and the number of branches of the pipeD; but any number of openings C and branches may be used in the deviceshown in Fig. 1, or any number of single burners shown in Fig. 5 may beused to attain the required heating capacity.

Having thus described my invention, I claim- 1. Thecombination of apartition-wall K, in which the opening K `is formed, andavaporizing-retort C, invwhich the centrally-located and inclined orfunnel-shaped openings C are formed, said retort being provided with theflanges C3, surrounding said openings C', and said partition-wall andretort dividing the chamber into which this apparatus is placed into twoapartments, theopenings C through the retort C forming the onlycommunication between the two apartments into which said chamber isdivided, with asuperheating-chamber G, the under side of which is solidand forms an abutment, and said chamber G being provided with acurvedpassage G', which communicates with the retort C, and a pipe D',communicating with said passage and extending down through the retortand within the range of the fire, and openings d2, formed in said pipe Dbelow said retort, substantially as shown and described, and for thepurpose specified.
